Moral - Meta ethics Flashcards
What is cognitivism?
- Moral judgements express cognitive mental states, e.g. beliefs
- They aim to describe reality
- Statements can be true or false
What is non-cognitivism?
- Moral judgements express non-cognitive mental states
- They do not aim to describe reality
- They are not capable of being true or false
“Boo! Murder!” “Don’t torture animals!”
What is moral realism?
There are mind-independent, external moral properties and facts – e.g. “murder is wrong” is a moral fact because the act of murder has the moral property of wrongness
What is moral anti-realism?
Mind-independent moral properties and facts do not exist
Outline moral naturalism
Mind-independent moral properties exist as natural properties that are intended to be true or false (moral realist + cognitivist)
“Murder is wrong”
- expresses cognitive belief
- wrong is a natural property
Outline utilitarianism as a form of moral naturalism
- Reductive:good can be reduced to psychological property of happiness, bad can be reduced to pain (natural brain properties)
- Mill’s proof of utilitarianism: happiness is the good and the only good since other desires provide the ultimate end of happiness
Outline VE as a form of moral naturalism
- Non-reductive
- Ergon/function argument: can be interpreted as a discussion of natural facts, as it can be argued it is a natural fact that the function of humans is to reason, like the function of a knife is to cut
Outline the naturalistic fallacy against moral naturalism
Moore argues it is fallacious to equate goodness with a natural property
He argues that while pleasure and happiness are closely correlated, they refer to 2 different kinds of properties: natural and moral (this invalidates Mill’s proof since he concludes happiness (natural property) is good (moral property)) - can’t jump from natural to moral
Outline Moore’s open question argument against moral naturalism
It is an open question to ask
“Is pleasure good?”
However if good is the same as pleasure (as claimed by naturalism), the question would be closed since it would be asking, “is pleasure pleasure?”
What is moral non-naturalism?
Mind-independent moral properties exist as non-natural properties that are intended to be true or false (moral realist + cognitivist)
“Murder is wrong”
- expresses cognitive belief
- ‘wrong’ refers to non-natural property; non-natural properties cannot be reduced
Outline Moore’s intuitionism
Moral realist, cognitivist, moral non-naturalist theory that claims we know about non-natural moral properties through rational intuition; directly reflecting on the moral truth behind statements. Truth/falsehood of moral statements are self-evident
How does Hume’s fork attack moral realism?
Moral judgements are not relations of ideas, nor are they matters of fact, therefore moral judgements are not judgements of reason
What is Ayer’s verification principle as a criticism against moral realism?
For Ayer, a statement only has meaning if it is analytic or empirically verifiable - if a statement lacks these then it lacks meaning
“Murder is wrong”
Not verifiable or analytic
Pain of murder doesn’y make it ‘wrong’ (hence no naturalism)
Can’t prove non-natural properties like intuition (hence no non-naturalism)
Outline Hume’s is-ought gap against moral realism
Hume distinguishes moral and factual statements: moral statements express what we ‘ought’ to do while factual statement express what ‘is’ true or false
Ought statements are non-cognitive
Is statements are cognitive
Therefore we can’t derive ‘ought’ moral statements from ‘is’ factual statements
Outline Mackie’s argument from relativity against moral realism
Cultural variation in moral beliefs cannot be explained by realism - if mind-independent moral properties exist, they should be objective. Has one culture got moral reality? Or have cultures got different ways of life and their morals reflect that?
